    So my alarm siren wasn't making any noise when i arm or disarm the system

    Also didn't make any noise when i triggered the system

    When i locked the car the l.e.d rapidly flashed a few times, went solid red for a bit then began flashing like normal

    Opened up the siren, checked the batteries and they didn't have a full charge so presumed they were faulty

    I just bought another siren, from a trusted breaker, tested before shipping

    Connected it up to the car and still the same, no siren sound when arming, disarming or triggering the alarm

    Still going through the same l.e.d sequence of rapidly flashing, solid red then steady flashing as normal

    Anyone got any ideas?

    Have you tested the new siren from your seller by hooking it up to a power source before fitting to car ?
    Have you had a vcds scan for faults ?
    Also worth checking that the conecter that goes to siren is working.

    Not tested the siren but trust the seller

    No access to vcds in my area (checked the map on here)

    Have checked the wiring and connector with a voltmeter and it has power

    Wondering if the convenience unit isnt sending a signal to the siren when the alarm is going off

    Think I might have to set the alarm off whilst checking the connector with a multi meter and see if its sending a signal

    I may be wrong - but I think You can switch off the 'warning' beeps (so it only flashes the indicators) with VCDS. Maybe this has happened by accident - a Scan is probably required.
    Tricky - may have to go to the main stealer unfortunately......

    I rid read somewhere that you can turn off the arming and disarming beeps but when I purposely trigger the alarm system by making it think the car is being stolen the alarm siren should sound

    Dont really want go to the main steeler if I can help it, car is garaged at night and in a secure car park during the day so not too worried about sorting it asap
